The telephone isn’t the only timesaving technology that drives me crazy. The other day, I went to the supermarket. They had a new self-service checkout system. With this new device, I could scan my groceries myself instead of waiting in a checkout line. For some strange reason, these machines seem to hate me. Here’s what happened: I scan my item. The computer sits there stupidly and does nothing. Eventually it says, “Scan your first item.” But I already did! What do I do now? Scan it again and get charged twice? So I put my item in the bag.
